Made to fit on the muscle rack shelf system, and holds a single drill at various orientations. Features a vertical slot for easier access for long drill bits. Currently only tested with the Black and Decker drill system.

If you're making it yourself, you'll need at least 1 zip tie to secure it to the shelf. I personally use at least 2 for strength and durability. Otherwise the harsh cyclical loading will likely wear out the zip tie and tear it off the shelf. But 2-3 zip ties seem to last over a year now.
